Answer:

Option C: $30 is the original price of book.

Step-by-step explanation:

Let the original price of book be x

Given that:

Sale price = x - 40% of x

As it is given that the sale price was $18

So,

$18 =  x - 40% of x

By simplifying:

$18 = x - 0.4x

$18 = 0.6x

Dividing both sides by 0.6:

x = $18/0.6

x = $ 30

So the original price of book will be $30

i hope it will help you!

<u>Answer: </u>

Option (c) $30.00

<u>Explanation: </u>

Let the original price be $x

Given the rate of discount is 40%

Selling (or sale) price of the book is = $18

The original price is calculated by the formula,

Selling Price = Original Price(1 – r%)

Substituting the values in the above equation,

18 = x (1-\frac{40}{100})

18 = x (\frac{60}{100})

x=\frac{1800}{60}

Therefore, x = 30

Hence, option (c)is correct

ELEN [110]
Jasmine is baking and selling cupcakes for $15 per dozen.
Let x be the number of dozens of cupcake made by Jasmine.
Her total sales= Sales Per Dozen X Number of Dozens of cupcake sold
= $15 X x = $15x
Since she would like to make more than $120 in cupcake sales.
It means her total sales must be greater than $120.
15x>120
x>120/15
x>8
The number line attached represents the solutions to the situation.
All integers to the right of 8 (excluding 8) satisfies the situation.

Hope this helps!:)

The sum of a number and three more than twice that number is 27 .what is the smaller number ?
satela [25.4K]

number - N

The sum of a number and three more than twice that number is 27.

N + (2N + 3) = 27

what is the smaller number ?

N + 2N + 3 = 27

3N = 27 - 3

3N = 24

N = 8

Check

N + (2N + 3) = 27 = 8 + (2x8 + 3) = 8 + 16 + 3 = 27

Triangle ABC, with coordinates A(2,3), B(3,5), C(7,4), is dilated by a scale factor of 2. What are the coordinates of the dilate
nevsk [136]
Answer is choice C

"Dilate with a scale factor of two" means "multiply each coordinate by two"
A = (2,3) turns into A' = (4,6)
B = (3,5) turns into B' = (6,10)
C = (7,4) turns into C' = (14,8)

Side Note: this quick shortcut only works if the center of dilation is the origin (0,0). If the center of dilation isn't the origin, then you will have to do a translation (shifting) before you can use the trick, and then you'll have to shift back. The idea of the shifting is so that the center of dilation becomes the origin on a temporary basis. Because no mention is made of the reference center, it is assumed to be the origin by default.
